Can you really make money from copy trading?

So, I've been hearing a lot about copy trading in the world of cryptocurrency and finance. But I have to ask, can you really make money from it? Is it just a fad or is there real potential for profit? I understand that it involves following the trades of successful traders, but how do you know if the traders you're copying are actually good? And what about the risks involved? Can you give me a rundown of the pros and cons of copy trading, and maybe some tips for making the most of it if it's something I decide to try?
